According to economists at the World Bank, China is predicted to overtake the United States as the world's largest economy by the end of this year.
However, we should be careful with such predictions. They are usually based on gross domestic product (GDP), which is the total value of all goods and services produced in a country in a year.
But this isn't the only way to measure economic strength. Because China's population is four times as large as that of the US, it still means that ordinary Americans are far wealthier than ordinary people in China.
We need to look at other factors, such as access to safe food, water and air. We should also consider the environmental impact of economic growth.
As China becomes an increasingly important player in the global economy, it will also assume a greater role as a world leader. Let's hope it can use this role to help create a better world for everyone.
